ANTISKID DEVICE.

To all whomit may concern:

Be it known that we, Ertoexe Jasi'n and Srrve Karena), subjects of the King of Hungary, county of Fayette and State of Pennsvlvania, have invented certain new and use ul Improvements in Antiskid Devices, of which the following is a specification.

This invention relates to certain new and useful improvements in anthskid devices for automobiles and like vehicles, and has for its object, the provision of novel and effective means for preventing the skidding or lateral movement of wheels on slippery sur faces.

The invention while adapted to pneumatic tired or other type of wheels. is particularly adapted for use in connection with wheels having what are generally known as cushion tires, and among its objects, aims to provide for such wheels an anti-slipping armor which may be readily attached to or applied to the tire, securely fastened to the wheel, and as readily removed when desired.

The invention has for its further object to provide an armor for pneumatic or cushion tires built up of similar or counterpart sections having a novel 'oining means which will permit of the required flexibility of the armor and also permit of the move ment of one section with respect to an adjoining section or adjoining sections without danger of breaking or damaging the connection between the sections.

Other objects of the invention will up rear as the invention is hereinafter more fully described and claimed. and in describing the invention in detail, reference will be had to the accompanying drawings forming a part of this specification, and wherein like numerals of reference indicate like parts throughout the ditterent views, in which Figure l is a view in side elevation of a cushion tired wheel, partly broken away, with an armor constructed in accordance with our invention applied thereto, Fig. 2 is an enlarged cross-sectional view of the same. Fig. 3 is a partial longitudinal sectional view showing the meeting ends of two of the sections of the armor, and. Fig. 4 is a detached detail perspective view of a part of one of the armor sections.

in the illustrated embodiment of our 1n- Specitlcatlon of Letters Patent. Application filed February 14, 1914. Serial No.

residing at Uniontown, in the- Patented Aug. 18, 1914.

vention, we have shown an armor constructed in accordance with our invention as applied to a wheel having a cushion tire, 5 designating the cushion tire secured to the telly (5 of the wheel in any desired or approved manner.

An armor in accordance with our invention is preferably made in a series of sections. These may be as many or as' few in number as desired, though we have found it advantageous to build up the armor of quite a number of sections, substantially as many as there are spokes in the whee as this provides for a greater flexibility of the armor.

The sections of the armor are duplicates one of the other, each being formed on the arc of a circle, so that they will tit with the tire to which the are applied. These sections are prefera ly formed of metal, and while they may be stamped out, they are preferably cast, and each section com rises a plate member 7 that is curved both ongitudinally and transversely, the arc transversely of the plate being of course, consid erably greater than the longitudinal arc, that the plate may neatl fit with the pcri hery of the tire to wl iich it is applied. T e convex or outer face of this plate is provided with pointed projections 8. which may have any desired contour, bu desirably of pyramidal contour as herein shown, and which are arran ed referably in rows on the outer face of t e late and extending longitudinally of the plate, the preferable arrangement of these rows being one in the central longitudinal line of the plate, and one or more, preferably at least two rows on each side of the central row, the two rows which lie adjacent the central longitudinal row being spaced some distance farther from said central row than the remaining rows are spaced from each other, as best seen in Fig. 2 of the drawings. At each end of each section is an outwardly extending end plate or flange 9, provided near each side with an oblong slot 10, and substantially midway between the ends of each section, the plate- 7 has inwardly-projecting side arms 11. that are sutliciently long to project inward beyond the felly, and have apertures in their inner ends to receive a cross bolt 12 by means of which the sections are fastened securely onto the wheel. The sections are flexibly or loosely joined together by means of rings 14 through the oblong apertures or slots in abutting end flanges of the sections, and when the complete armor has been placed around the tire, the abuttin ends of the last two sections are prefera l v joined by bolts 15 through the 0blong slots of such two abutting sections, although the looseconnections may be employed at all joints between the sections.

The provision of the oblong slots. and the rings to connect two adjoining sections together provides for movement of one. section without damaging the connection which joins it to the adjacent section, the slot and ring connection affording a considerable range of movement of the sections independently of each other. without danger of shearing the connecting rings. The projections on the sections besides serving: to prevent skidding of the \vheehalso atl'ord means for giving a greater traction thereto as will be obvious. and while we have described in detail a pret'cral'fle embodiment of our in vention, it will be evident that in the practice thereof various slight changes may be made in the details thereof, without departscope of the invening from the spirit and and claimed.

tion as herein described LlNWJMi Having fully described our invention. what We claim as new and desire to secure hyletters llatent of the United States is A tire armor comprising a. plurality of segmental sections of equal length fitting together end-mend to cover the entire periphery of the tire, and having projectlons on their outer faces. each of said sections being curved both longitudinally and transversely, and provided at each end with an outwardly projectingflange, the-flanges of one plate abutting those of adjacent plates, and each formed with an elongated slot, the slots of abutting flanges registering, rings extending through said slots to flexibly connect the flanges, and each section having a pair of inwardly extending arms embracing the wheel on opposite sldes at: a point midway fellv between the flanges on the section. and crossbolts extending transversely of the inner face of the telly, connecting said arms.

lln testimony whereof we atiix our signatures in presence of two witnesses.
